JACOB. FINE, OF LOUISVILLE, KENTUCKY.

APrARA'rUs FOR APPLYING FASTENERS.

To all whom it may concern: Be it known that I, JACOB FINE, a citizen of the United States, residing at Louisville,

in the county ofJefferson and State of'Kenholder or fastening device disclosed in Patout No. 1,316,779, issued September23, 1919. Ordinarily, the labels, tags or the like on the inside of cloth and other caps are attached by being sewed on, whereas the patented fastening device is a thin sheet metal disk having outstanding spurs on both sides, which are so arranged that the spurs on one sidemay be driven into the cap or other article, whereas the label, tag or other article is applied by being impaled on the spurs on the other side. The invention has for its object to provide a simple, rapid and efficient implement for applying the fastening devices, and to this end it consists in a novel combination and arrangement of parts to be hereinafter described and claimed.

In order that the invention may be better understood, reference is had to the accompanying drawings forming a part of this specification, and while the preferred embodiment of the invention has been disclosed, it will be understood that various changes, and modifications may be made without a departure from the spirit and scope of the invention as claimed hereinafter. I

In the drawings:

Figure '1 is a plan View of the machin with certain parts broken away; Fig. 2 is an elevation with parts broken away; Fig. 3 is an enlarged elevation of'a detail, partly in section; Fig. 4 is a bottom. plan view of the machine; Fig. 5 is a section on the line 55 of F ig.,2; Fig. 6 is a section on the line 6-6 of Fig. 1, and Figs. 7 and 8 are sections on the lines 7'? and 88, respectively, of Fig. 3.

Referring specifically to the drawings, 10 denotes a base or table which carries-the various elements of the implement, and is provided with supporting legs or feet 10. From the base rises a standard 11 having'at Specification of Letters Patent.

Patented; Oct. 12, 1920.

Application filed December 6, 1919. Serial No. 342,926.

the top a support 11 for a vertically reciprocatory stem 12 carrying at its lower end a plunger 13, and provided with a rack 14. A pinion 15 is in mesh with the rack 14, where by the stem 12 is 'reciprocated to operate the plunger 13. The pinion 15 is on a shaft 16 supported in a suitable bearing on the standard 11, and provided with an operating handle 17. A spiral'spring 18 isconnected to the shaft 16 in sucha mannerthat it turns the same in a direction to impart an upward or return stroke to the plunger'stem 13 through the pinion 15 and the rack 14, the working stroke being in the opposite direction, or downward.

The function of the plunger 13 is to afiix the fastenin devices disclosed in the Patent No. 1,316,739 hereinbefore referred to.

. These devices are small sheet metal disks 19 having a pair of outstanding pliable'spurs 20 on one side, and another pair of such spurs, 21 on the other side. The disks are connected in the'form of'a strip as shown in Fig. 3. In fastening the'label, tag or the like to the cap or other part, one or more disks are first affixed to the cap, .on the inside thereof, by one set of spurs, and the label is then impaled on the other set of spurs. The implement is shown equipped for the simultaneous application of four disks, this being the number usually required to affix the label, but the structure may be modified to operate on anyother number of disks.

"Each strip of disks is mounted in a suitable magazine 22 carried by a slidable guide and carrier 23 for the strip; The" magazine is made fast to one end of the-carrier 23, and on the other end is a standard 24' supporting a' vertically slidable driver bar 25. The carrier 23 has a guide. channel 26:for the strip of disks, extending from the outlet of 'the magazine 22 and terminating beneath the driver bar 25, so that one disk after the other tion of the standard in which the driver bar, works projects beyond the end of the guide channel 26 from which theidisk to be severed projects, whereby a second shearing edge is produced below the disk and in line with V the edge 25", to cooperate therewith.

The driver bar 25 operates a device for feeding thestripof-disksforwardly a distance to project one disk after the otherto be operated on. This feeddevice comprises the following parts: I

From the {back of the driver bar, 25, through a slot in the standard 24, extends an arm 27 having at its outer end a cam edge 27. To a post 28 rising from'the member 23 is pivoted,intei'mediate its ends, a lever 28, the pivot being shown at 28 One end of this lever has an abutment 29 in the form of a roller which isengageable by the cam surface :27 The other end of the lever carries a feed pawl 30, thesame being pivoted to the lever, as shown at30. The feed pawl may be in the form of a fork so as to come between two adjacent disks. The post 28 also supports a spring, one end 31-of which presses upwardly against. the

arm 27 to elevate the driver bar 25, and

the other end 31 presses against the lever 28 to swingthesame 1n a dlrection giving the pawl 30 its return stroke.

When the driver bar 25 starts to go down to sever a .disk from the strip, the cam sury face 27" presses against the roller 29 and 29 clears the cam surface 27 lVhen the driver bar 25 makes its upward or return stroke, the spring end 31 swings the lever.

28. ina direction to again bring the roller 29 under the cam surface 27 and to g ve the pawl 30 its returnstroke.

The driver bar 25' aflixes the disk to the I cap'by pressing thespurs 20 thereinto, these spurs being at ,the bottom. In order that the driver bar may clear the'top spurs 21,

itais recessed on opposite: sides as shown The'capltowhich the label is to be applied is placed on an anvil 33 at the center of the table 10 and directly beneath the I plunger 13. V

The driver bars 25 are simultaneously operated in the manner hereinbefore described by the plunger 13, and after thedisks are applied to the cap, the label is placed on- 1 top of the disks, and the plunger 13 is again lowered to impale the label on the topbarbs or spurs 21, the members 23 being first swung to carry the driver bar 25 clear of the anvil 33,so that when the plunger descends it comes directly in contact with the label and the disks.

The following means are provided for swinging or retracting the members 23.

Each member 23 is held by a setscrew 34L 7 or base 10, and on thepivot 37 is a sector 7 gear38'meshing with a similar gear 39 pivoted to the post 36, as shown at 39 and ere tending downwardly through a slot 40 in the table. At the center of the table 10, on the under side thereof, is journaled, as shown at 41,'a disk l2 connected by a rod or link 43 to the lower end of the sector gear 39. The disk 42 has an operating hall die 44:. The swinging support of each member23 has its sector gear 39 connected by a rodor link to thedisk 42, and hence when the latter is rotated, all of said members swing together. The pivots 3'? are horizontal, and hence the members 23 may be swung upwardly to clear the anvil 33.

V In order that two diametrically opposite ones of the members 23 may be placed in various positions to adapt the implement to labels of different shapes necessitating a different grouping of thedisks 19, the following devices are provided: 7

r 7 Two diametrically opposite posts 36 carry a pivoted arcuate bar45, and the latter sup- I ports the block 35, said block however not belng pivoted. The bar 45 is operated by a sector gearing in" the same manner and for the same purpose as the other blocks 35 whichare pivoted directly .to the. posts 36. The bars 45 are curved on an are having for its center the center of the table 10,and as the blocks 35 seating on said bars are slidable thereon, said blocks can be slid toward and from the other blocks for the purpose hereinbefore set forth, they being held in adjusted position by set screws 46. i The anvil may be made rotatable, with a center depression toreceive a button on top of the cap at the center.
